In our solar system has magnetic pole reversal
Earth's North Magnetic Pole is where the Earth's magnetic field points downward into the planet. It is constantly moving due to changes in the planet's molten iron core. Currently, it is located in the Arctic region of North America.
The space surrounding a magnet in which the magnetic force acts is called a magnetic field. The magnetic field is the region where magnetic forces are generated and can influence other magnetic materials or moving charges.
The terms, 'Magnetic North' and 'Magnetic South', are used to differentiate between their locations and those of 'True North' and 'True South'. 'Magnetic North' and 'Magnetic South', are places and have nothing whatsoever to do with the magnetic polarities associated with these places. The magnetic polarity at Magnetic North is a south pole, and the magnetic polarity at Magnetic South is a north pole. This is why the earth's magnetic field leave from Magnetic South and enter at Magnetic North -the directionof the field being the direction in which a compass needle will point.
St. Cloud, Minnesota, is located at a magnetic declination of approximately 1 to 2 degrees west of true north. This means that magnetic north, as indicated by a compass, is about 1 to 2 degrees west of true north in that area. However, this declination can change slightly over time due to shifts in the Earth's magnetic field. For precise navigation, it's always best to check the most current magnetic declination data.
North seeking gyro is the best gyroscopic surveying instrument for the mining and Oil & Gas industries. As it is a North-Seeking Gyro, all measurements are in reference to geographic North. Unlike other downhole survey or magnetic tools, it is not affected by magnetic interference. When it comes to directional surveying where precision and accuracy are of paramount importance, especially in areas with strong magnetic influences, true North-seeking gyro while drilling is the only solution. It can run inside casing without worrying about the magnetic influences causing deviations and errors.SPT true North-seeking gyro while drilling uses quartz technology, more rugged and highly precise in operation.

Earth's north magnetic pole is the point on Earth where the planet's magnetic field points vertically downwards. It is currently drifting towards Russia at a rate of about 10 kilometers per year. This pole is different from the geographic North Pole, which is the point where Earth's axis of rotation intersects its surface.

Our planet behaves as though a giant bar magnet is buried deep within the earth, and lying slightly out of alignment with the earth's axis of rotation. The points where this imaginary bar magnet's magnetic field lies perpendicular to the earth are named Magnetic North and Magnetic South respectively. These points do not coincide with the earth's geographic poles, which are called True North and True South respectively. It's very important to understand that 'Magnetic North' and 'Magnetic South' describe locations, and have nothing whatsoever to do with their magnetic polarities. In fact, these locations are not fixed, but constantly move relative to True North and True South, and the locations must be taken into consideration for the purpose of navigation.A freely-suspended magnet (or a compass needle) will align itself with the earth's magnetic field and will always come to rest pointing in a Magnetic North - Magnetic South direction. Because of this, one end of the magnet was originally named its 'North-Seeking Pole', while the other end was named its 'South-Seeking Pole'. Over time, we have dropped the word 'seeking' from these expressions, and now call the ends of a magnet (or compass needle) its 'north pole' and its 'south pole' which, by common consent, are used to identify the magnetic polarities of a magnet. Because 'unlike poles attract', this means that the magnetic polarity of Magnetic North (i.e. the location) must be a south pole, and the magnetic polarity of Magnetic South must be a north pole.To summarise, the terms 'Magnetic North' and 'Magnetic South' are locations so-named to differentiate them from 'True North' and 'True South' for the purpose of navigation. Because the north pole of a magnet or compass needle is attracted towards Magnetic North, that location's magnetic polarity is south. And, of course, the magnetic polarity of Magnetic South location is north.From geological records obtained from magnetized rock strata and other natural materials, it is well-known that the magnetic poles have actually "flipped over" several times during the many aeons of the earth's long history (although not during man's existence). Should this do so again in the future, it will have no affect whatsoever on the locations or on naming of 'Magnetic North' and 'Magnetic South', although their magnetic polarities will, of course, reverse!For more information see the Related links shown below.
The equation that best describes the induced emf due to the movement of a rod in a magnetic field is given by Faraday's Law of Electromagnetic Induction, which states that the induced emf () is equal to the rate of change of magnetic flux () through the loop formed by the rod. Mathematically, it can be expressed as -d/dt.
